* Handling of Ethernet PHY's

* PHY's communicate with an EMAC either through

* a Media-Independent Interface (MII), or a Reduced Media-Independent Interface (RMII).
|
||||||
|
* The EMAC can poll for PHY ports on 32 different addresses. Each of the PHY ports
|

|
* shall be treated independently.
